CLEANER, SAFER and better TASTING water!

Our coagulants destabilise the fine colloidal particles occurring in water that carry bacteria, viruses and protozoans. We do it with far lower chemical treatment than other methods. The positive charge rates of ACHLOR GOLD are the highest in the industry which means they cost a little more per litre, however the exceptional performance allows particles to be removed more effectively and efficiently.
